Sh1 94v-0 Datasheet __top__
The 94V-0 rating is part of the standard established by Underwriters Laboratories (UL) to test the flammability of plastic materials. It is one of the highest safety ratings available for electronic components.
When you see stamped on a green, blue, or black circuit board, treat it as a certificate of flame safety and origin rather than a part number. To advance your troubleshooting, shift your focus away from this stamp and search instead for the UL "E" number to identify the factory, or the proprietary motherboard model number to find a working circuit diagram.
There is no single "SH1" integrated circuit datasheet, because SH1 identifies the board substrate itself, not the active components soldered onto it. What is "94V-0"?
When troubleshooting electronics, sourcing components for a new project, or examining a printed circuit board (PCB) from a consumer device, you might encounter the cryptic marking: . This combination of letters, numbers, and a dash is not random code, but a crucial set of safety and manufacturing identifiers. sh1 94v-0 datasheet
If you see on a board you are servicing or designing, you can be confident that the substrate is a high-quality, flame-retardant FR-4 material. It is suitable for high-density circuits and power-sensitive applications where heat management is a priority.
Standard SH1 connectors use nylon 66 (UL94V-0 equivalent). However, the specific "SH1 94V-0" variant uses reinforced engineering plastics that are halogen-free and meet RoHS compliance regarding flammability.
When you search for an "SH1 94V-0 datasheet," you are essentially looking for the technical documentation of a product that uses the or has that safety certification . It is highly unlikely you will find a datasheet titled "SH1 94V-0.pdf". Instead, the "94V-0" rating will be a key feature listed in the datasheet of a specific component, PCB assembly, or raw material. The 94V-0 rating is part of the standard
In many cases, boards marked with "SH1 94V-0" (often alongside UL file numbers like ) are specific components like USB interface boards or power management plates used in consumer electronics such as Samsung, Lenovo, and Huawei tablets. What is SH1 94V-0?
Search for that specific alphanumeric code followed by the word "datasheet" to get pinouts, voltages, and operational parameters.
Glowing combustion must not exceed after the second flame application. Common Substrate Usually FR-4 (Flame Retardant 4) glass-reinforced epoxy. Why This Rating Matters To advance your troubleshooting, shift your focus away
: This is typically a manufacturer's internal code or model series. For example, "SH1" is frequently seen on main boards for televisions, monitors, and even automotive USB modules. : This is a UL 94 flammability rating
| Rating | Orientation | Afterflame Time (Single) | Flaming Drips Allowed? | Typical Application Context | | :--- | :--- | :--- | :--- | :--- | | | Vertical | ≤ 10 seconds | No | High-reliability PCBs in power supplies, automotive, industrial controls | | 94V-1 | Vertical | ≤ 30 seconds | No | Lower-risk enclosures, general-use components | | 94V-2 | Vertical | ≤ 30 seconds | Yes | Components where drips do not pose a fire risk (e.g., encapsulated indoors) | | 94HB (Lowest) | Horizontal | Varies (burn rate) | N/A | Simple toys, disposable electronics, non-structural parts |
